MEANSgFo afl-.oem N VALVES.

SPECIFICATION forming' part of Letters Patent No. 280,912, dated July10, 1883.

I Application filed October G, IES-2. (No model.)

Be it known that I, PATRICK CoNNoLLY, of Brooklyn, in the Vcounty ofKings and State of New York, have invented certain new and usefulImprovements in Means for LockingValves, of which the following is aspecication.

My improvement is intended more particularly for screw-valves oranalogous valves eontrolling the supply of gas, steam, water, and otherfluids to dwellings, factories, and the like where taxes are demanded,and it is some times necessary for the proper authorities to close thevalves and to keep them closed against the wishes of the` owner oroccupant of the building.

The invention may be employed to lock similar or analogous valvescontrolling the flow of I provide a loosely-iitted case, which coversthe hand-wheel or other turning device, and also all the exposed portionof the shaft or stem of the valve, and engages under the ange of thestuing-box or other suitable enlargement'o'r projection on thexedvportion ofthe apparatus. I- make this case in two parts and providea padlock or other lock, which rmly engages them together and forbidstheir separation so as to allow access tothe hand-wheel.

The case must be loose, so that turning it around Will have no effect onthe valve.

The following is a description of what I consider the best means ofcarrying out the invention.

Figure l is a front elevation, and Fig. 2 a rear elevation, of thedevice complete as applied to the operating means of an ordinary valve.Figs. 3 represents one of the halves of my case detached.v Figs. 4 and 5show a modiiication. Fig. 4 is a side elevation, and Fig. 5 acorresponding frontelevation. A

Similar letters of reference indicate corre spending parts in all thefigures.

A is an ordinary valve-casing, and A the neck or extension thereof,which surrounds the valve-stem and carries at its end an ordi narystu'liingbox, A2. The valvefsteni e eX-` tends through this stuffing-boxand is operated by a hand-wheel, E. The stuffing-box A?, stem, and wheelmay be'of any ordinary or suitable construction, and are indicated indotted lines in Figs. l and 2.

B and G are the two halves of my ease. Re

sufficient hole therein, which, when the case is closed together, may besecured by a padlock, D. B and O are properly matched to each other, andinclose a cavity a little larger than the stuffing-box, stem, andhand-wheel.

They are preferably of a form approximating to these parts. The loweredge of each part B and C is equipped with an internal lip, B C3, whichis adapted to engage under the stuffing-box. This insures that any forceapplied to my case to lift it shall be received, not on the hand-wheel,so as to make a friction which might, under some possible conditions,turn the valve, but on the stuffing-box, vso that, at the worst, thestufingbox only will be tightened or loosened by any such turning of mycase.

In the modiiication shown in Figs. 4 and 5 only a single hinge or eye isprovided at the back of the case. The front of the case is equipped withlugs or perforated lips to receive the padlock, as in the other form,but the lips are placed lower and the space above is utilized to formlocking projections and recesses G, which, when the device is closed,engage with each other and aid to maintain the parts againstdisplacement. The case, being made with two enlargements covering twoprotuberances or enlargements on the valve and connections, willconstitute a covering which will not be removed by the disengagement ofone of the enlargements, but upon one being broken the other will serve.

Modifications may be made in many of the details. With stuffing-boxeswhich are liable `to comento rest at different heights, my case mustbemade of ample depth to accommodate the 'parts in all positions. It isimportant that the case shall fit so close that nothing may be extendedup fronifbelow or extended inward from the joint `between the two partsto allow the casete be engaged with the hand-wheel, the success of thedevi ce depending on its being allowed to turn freely without operatingthe hand -wheel or equivalent device which controls the valve.

The invention maybe used for other pur poses than those above indicated.I believe IOO that it may be applied successfully on oil tanks and agreat number of other vessels which, from their nature or position,cannot beV Well guarded against unauthorized persons.

Instead of the padlock'D, I can iita lock in one of the parts of thecasing B C and cause its bolt to engage With the other part, as Will lbe obvious.

I claim as my invention- 1. The combination, With the valve andconnections having the stuffing-box or other enlargement A2 and theoperating means E, con-` stituting a second enlargement at a differentheight, of the locking-case A, having an enlargement for .covering thepart E, and another Y enlargement for covering the part A2, and adiminished portion between them, as herein set forth.

2. In combination With a valve-case, A, having Va stuffing-box, A2, oranalogous enlarge ment on the neck, the casing B C, made in tWo partshinged together and ,providedzwith the internal lips, B3- C3, engagingunder the proj ection Af", and arranged to not only inclose thevalve-operating means E and prevent access thereto, but also to relievethe latter from frictional turning force, as herein specified.

3. The locking-case B C, having one or more eyes or hinges, B G',- lugsB'l C2, and -projections and recesses G, in combination with the lock D,valve-case A, stem e, and operating means E, all substantially as hereinspecified.

In testimony whereof I have hereunto set my hand, at New York city, this28th dayl of Sep# tember, 1882, in the presence of tWo subscribingWitnesses.
